During the second week of flowering for Purple Kush, here’s what you can expect and steps to ensure a successful grow:
Plant Development
1. Bud Formation: Small pre-flower buds (calyxes) will begin forming along the nodes. Pistils (white hairs) may be visible.
2. Stretch Phase: The plant will still be stretching, potentially doubling in height as it transitions into full flowering mode.
Care Tips
1. Lighting: Ensure a consistent 12/12 light cycle. Use strong flowering lights (HPS, LED) with red spectrum dominance.
2. Nutrients: Transition to flowering nutrients with a higher phosphorus (P) and potassium (K) ratio. Avoid overfeeding nitrogen to prevent leafy growth.
Example: 1-3-2 NPK ratio is common in flowering.
3. Watering: Keep watering consistent but avoid overwatering. Allow slight drying of the topsoil between watering.
4. Temperature & Humidity:
Ideal temperature: 65–80°F (18–26°C).
Humidity: Reduce to 40–50% to prevent mold/mildew as buds develop.
Training
If you’re doing any low-stress training (LST), finish this early to avoid stressing the plant during full bloom.
Remove any dying or large fan leaves blocking bud sites to improve light penetration.
Monitoring
Watch for pests like spider mites and early signs of mold or nutrient deficiencies.
Look for healthy, vibrant leaves and steady growth in bud sites.
By week 2, your Purple Kush should show noticeable progression in flower development, setting you up for a good yield in the weeks to come.
